Using dashboard stickies?

I can't seem to get Dashboard sticky notes to work properly. When I drop a sticky into the Dashboard, I can enter text to it, but when I close the Dashboard and bring it back again, I can't. Single/double/command/option/shift-clicking all do nothing - the input cursor doesn't appear in the sticky. I have to either delete it and recreate it, or drag another sticky from the widget dock.

Is this a bug, or am I doing something wrong?
